摘要

Semiconductor quantum dots have been intensively investigated because of their fundamental role in solid-state quan-tum information processing.The energy levels of quantum dots are quantized and can be tuned by external field such as optical,electric,and magnetic field.In this review,we focus on the development of magneto-optical properties of single InAs quantum dots embedded in GaAs matrix,including charge injection,relaxation,tunneling,wavefunction distribution,and coupling between different dimensional materials.Finally,the perspective of coherent manipulation of quantum state of single self-assembled quantum dots by photocurrent spectroscopy with an applied magnetic field is discussed.
